How can I tell if my driver's license is REAL ID compliant?
REAL ID-compliant cards carry a marking, such as a gold star, near the top of the card; if you are unsure, check with your state's DMV.
Look at the top of the card. TSA says REAL ID-compliant licenses and ID cards carry one of the approved markings near the top, and a DHS fact sheet describes it as a gold star or similar mark, generally in the top right or left corner. According to TSA, a card without such a marking is not REAL ID-compliant and can't be used as your ID to board a commercial flight.
The exception is an Enhanced Driver's License or ID card, issued by only five states: Michigan, Minnesota, New York, Vermont and Washington. TSA accepts it as an alternative to REAL ID, and most of these cards don't carry the star. They show an image of the U.S. flag instead.
If you can't tell whether your card qualifies, TSA and DHS both point you to your state's DMV or equivalent agency.
